The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 717-200 airplanes, certificated in any category, as identified in Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes. This AD was prompted by a report of a nose landing gear-up landing caused by the failure of the upper lock link assembly. This AD requires repetitive inspections for cracking of the upper lock link assembly and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified by paragraph (h) of this AD: At the applicable times specified in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025, do all applicable actions identified in, and in accordance with, the Accomplishment Instructions of Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025.
Note 1 to paragraph (g): Guidance for accomplishing the actions required by this AD can be found in Boeing Alert Service Bulletin 717-32A0043, dated February 12, 2025, which is referred to in Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025.
(1) Where the Condition and Compliance Time columns of the tables in the “Compliance” paragraph of Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025, refer to the original issue date of Requirements Bulletin 717-32A0043 RB, this AD requires using the effective date of this AD.
(2) Where the Condition column of table 1 in the “Compliance” and “Accomplishment Instructions” paragraphs of Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025, specifies all airplanes with an Upper Lock Link assembly that has not been overhauled, as of the Original Issue date of Requirements Bulletin 717-32A0043 RB, in accordance with OHM 32-21-2, Revision No. 63 dated July 01, 2024, or later Boeing approved revisions published on New Maintenance Performance Toolbox (nMPT), that condition does not apply to an Upper Lock Link assembly that was manufactured after December 31, 2001.
(3) Where the Condition column of table 1 in the “Compliance” and “Accomplishment Instructions” paragraphs of Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025, specifies “All airplanes with an Upper Lock Link assembly that has been overhauled”, this AD requires replacing that text with “All airplanes with an Upper Lock Link assembly that was manufactured after December 31, 2001, or has been overhauled”.
(4) Where note (a) of table 1 in the “Compliance” and “Accomplishment Instructions” paragraphs of Boeing Alert Requirements Bulletin 717-32A0043 RB, dated February 12, 2025, defines a serviceable Upper Lock Link assembly as “one that has been overhauled”, this AD requires replacing that text with “one that was manufactured after December 31, 2001, or that has been overhauled”.
